WHEELER M. MORRISON, OF TOIVER HILL, ILLINOIS, ASSIGNOR OF ONE-HALF TO DAVID O. MILLER, OF SAME PLACE.

HORSE-DETACHER.

SPECIFICATION forming part of Letters Patent No. 402,097, dated April 23, 1889.

Application led January 3l, 1889. Serial No. 298,167. (No model.)

To a/Z whom, t may concern.-

Beit known that I, WHEELER M. MORRISON, a citizen of the United States of America, re-

siding at Tower Hill, in the county of Shelby and State of Illinois,'have invented certain new and useful Improvements in Horse-Detachers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art t which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in horse-detachers, the same being designed more especially as an improvement upon Patent No. 391,381, dated October 16, 1888; and my invention consists. in the construction and combination of the parts, as will be hereinafter fully set forth.

In the accompanying drawings, Figure l is a perspective view. Fig. 2 is a sectional view. Fig. 3 is a sectional view of a modification. Fig. 4 is a detail perspective view.

A refers to the pole or tongue, which has pivotally attached thereto a'singletree, B, the connection between the pole and singletree being made by means of a hollow bolt, a, the upper and lower ends of this bolt being either upset or screw-threaded to engage with nuts or washers. This bolt a also passes through a perforation in the rearwardly-exteuding strap a', the rear end of the strap being attached to the pole by the ordinary bolt and nut.

The singletree B is provided at its outer ends with hollow bolts b, which serve to connect the whiffletrees C thereto, so that they can have a pivotal movement thereon. The whifletrees O are provided with longitudinal recesses c, within -which lie bars h. These bars at their outer ends have hook-shaped portions c', which serveto hold the traces upon projecting ends CZ of the whiflletrees when placed thereon, and ,when the bars are slid outwardly the traces will be forced off of said ends. The inner ends of these bars h have angular heads h', which provide upwardly-projecting inclined sides, and adjacent to the inner ends of these bars they are provided with notches h2, which engage with the inner ends of the covering-plates H. These coveringplates H are rigidly attached over the slot or recess in the whiffletrees, and are provided at their ends with rings or bands, which eln- 5 5 brace the ends thereof. Beneath the bars h the whiffletrees are provided with springs s, which will throw said bars upwardly, so that the notches h2 will engage with the inner ends of the covering-plates when said bars 6o are moved inwardly to abut against the ends d of the whiffletree.

I refers to a T-headed rod, the ends of the cross member thereof being beveled tocorrespond with the inclination of the upwardly 6,5 and outwardly projecting portions h of the bar h. The vertical member of this T-headed rod passes through the hollow bolt Z), and is secured in any suitable manner to the rod D. The rod D is pivoted .by a suitable loop 7o or bail, cl,to the singletree B, and beyond this bail the rod D extends downwardly, the ends thereof being bent horizontally and slotted for the reception of a pin or operating-lever attached to the pole for the purpose of 75 lowering the outer ends. of the rods to depress the T-headed rods I, and thereby cause the bars h to be moved or slid in the recess, thus detaching the traces from the whifletrees.

It will be observed that, owing to the con- 8o struction of the ends of the bars h and the beveled ends of the upper member of the T- headed rod, the inner ends of these bars h, which are held raised by pressure of the springs, are depressed to cause the notches h2 8 5 in the bars h to become disengaged from the ends of the plates H.

In Fig. 1 of the drawings I have shown a bell-crank lever, E, as passing through the pole and pivoted within a slot or opening, the 9o forwardly-projecting member of this lever having a pin which engages with the slots g gin the inner ends of the bars D. Instead of this construction, I may employ the arrangement shown in Fig. 3 ofthe drawings, wherein 95 the bell-crank lever E is pivoted above the pole, the forward member thereof being slotted to engage with the bent end of the pin F, which passes through the hollow bolt d, the lower end thereof being bent to engage with the roo slots g g, hereinbefore described.

G refers to a boXor casing having depending spring portions h2 h2, by means of which it is held upon the whietrees so as to cover the ends of the bars h and the T-headed rod. To the upwardly-projecting ends 7L of the bars 71, h are secured side plat-es, i c', against which the rod I will engage to prevent said rod turning.

Instead of employing covering-plates eX- tending from the end bands of the whifiletree inwardly, as shown, said covering-plates may be dispensed with and bands or straps used.

In practice a cord or strap is attached to the rearwardly-proj ectin g member of the bellcrank lever E, and extends either through the oor of the vehicle or over the dash-board, so as to be within easy access, and by drawing upon this cord all the traces will be detached from the whiffletrees and the horses released from the vehicle. Then it is desired t-o unhitch the horses, the rods D are simply pressed down, which movement will throw the traces oft the whiietrees. In harnessing, the eyes of the traces are passed into the loops c and the bars h pressed inwardly. Each bar 7L being independent of the other, the traces are not attached to the whiiiietrees simultaneously.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a horse-detacher, the combination, substantiall y as described, of the whifiietrees and singletree connected by hollow bolts, hooked bars h, mounted to slide 011 the whiftletrees and provided attheir inner ends with inclines, rods I, seated loosely in the hollow bolts and engaging directly with the inclines of the hooked bars, levers D, fulcrumed on the singletree and connected at their outer ends with the rods I, and a device connected with the inner ends of the levers to operate them simultaneously.

2. In a horse-detacher, the combination, substantially as described, of the whiietrees and singletree connected by hollow bolts, hooked bars h, mounted to slide on the whiiletrees and provided at their inner ends with inclines, rods I, seated loosely in the hollow bolts and engaging directly with the inclines of the hooked bars, levers D, fulcrumed on the singletree and connected at their outer ends to the rods I, and a lever connected at one end to the slotted inner ends of levers D.

3. The combination, with the singletree and whiffletrees constructed and arranged as described, of hooked bars mounted to slide in the grooves of the whiietrees and having at theirin ner ends upwardly-proj ecting inclined or beveled webs, rods I, seated between the inner ends of said hooked bars and provided with T-heads beveled to correspond to the bevel of the webs, levers D, fulcrumed on the singletree and connected at their outer ends to the rods I, and abell-crank lever fulcrumed on the tongue and having its forward end in engagement with the slots at the inner ends of said levers D, substantially as set forth.

4. The combination, with a singletree constructed substantially as shown and provided with a longitudinal recess, of the sliding bars 7L, having upwardly-projecting inner ends which are beveled, notches h2, which engage with the covering-plates H, and springs s, substantially as shown, and for the purpose set forth.

5. The combination, with a singletree, ofthe T-headed rod I, sliding bars 7L, said bars having their inner ends inclined and extended upwardly, plates it, attached to the upwardlyextended portions of the bars 7L, so as to lie over the upper portion of the T-headed rod, substantially as shown.

6. The combination, with the singletree provided with a longitudinal recess and sliding bars h, of covering-plates H and a box, G, having downwardly-extended members h3 h3, which are adapted to embrace the singletree to retain said boX in position, substantially as shown.

In testimony whereof I affix my si gnatu re in presence of two witnesses.

Y WHEELER M. MORRISON.
